Introduction

Juan Pablo Sanucci Pl 2 Standar level. Predation and natural selection simulation Design: Aim: The aim of this is to investigate wich of the breaks of three different species: Cucharita cucharita (spoon beak), Tenedoricus toritlla (fork beak), Cuchillaria cuchillaria (knife beak) is better for catching different types of food, like grass seeds and more. Variables: fix variable: the time(in seconds) and the floor. Independent variable: The type of beak. Dependent variable: This is the units of food collected. Method: 1) Set up any material needed. ...read more.

Conclusion

Also we have done it in the time we though and the results were fairly accurate. By our results we can tell if the species could survive or not in this type of habitat. The experiment was done correctly and with care, but the weakness could be that we didn't spread the food like we should so maybe the results aren't as accurate as they could. As a future experiment we should change the floor for a real ground and have more time for each beak so maybe the experiment would be more accurate and the result weren't to high like in some cases in this experiment. ...read more.
